Astronomers find a new exoplanet that has waterworld tendencies due to the presence of methane and carbon dioxide.
There are many exoplanets in space. However, nothing quite like this has been seen in a while. The James Webb Space Telescope has constantly been a source of new space discoveries, and now it has unveiled captivating details about TOI-270 d. It is anestled in the TOI-270 system. It is nothing short of a space spectacle, and could potentially be a “Waterworld with a boiling ocean.
But ammonia is highly soluble in water and would be depleted in the atmosphere if there were an ocean down below. “One interpretation is that this is a so-called ‘hycean’ world—with a water ocean under a hydrogen-rich atmosphere,” said Prof Nikku Madhusudhan, who led the analysis. But the revelations don’t stop there. There was also evidence of carbon disulfide at 2.3–3.0σ confidence levels on the exoplanet. There was also a potential inference of water at 1.6–4.4σ, depending on the data.
